Mapping our reliance on the tropics can reveal the roots of the Anthropocene

Projecting and managing the feedback between tropical deforestation and global Earth system dynamics, and identifying potential critical thresholds or tipping points, will be key to our species’ future on this planet. By understanding the major historical processes that underpin the origins of this interaction, and bringing natural and social systems together in interdisciplinary models, we can evaluate the degree to which past human impacts on tropical forests resulted in observable planetary ramifications that have left legacies for the twenty-first century and beyond.
